Light-emitting diode print head with staggered electrodes |
摘要 |
A light-emitting diode print head having a narrow LED array chip wherein the constituent LEDs of the array are arranged in a zigzag formation and driven using a differential timing arrangement that compensates for the offset of alternate LEDs in the printing line. The LED array comprises a plurality of light-emitting elements arrayed in a staggered configuration of odd and even numbered elements in parallel rows extending in a first, print line direction and a plurality of electrodes connected to the corresponding light-emitting elements and arranged in a mutually alternating orientation extending between the parallel rows at right-angles to the first direction and forming parallel rows of odd and even numbered electrode terminals interleaved between the even and odd numbered light-emitting elements, respectively.
